Application filed. July 2,

The present invention relates to joining means, such as bands or ringsfor joining or connecting sections of a heater or the like.

Among the objects of the invention is to provide a novel joining bandstructure adapted to fit sections of different sizes with out thenecessity of carrying different sized bands in stock, but which can bemade with the major or main part of the hand of a size to fit thesmallest heater section and adapted to receive a connected'segment toenlarge the band to the larger sizes of sec tions to be fitted orjoined. thus requiring the carrying in stock of only the small segmentsinstead of whole bands of different sizes. i

a The invention also comprehends the provision ,of novel means forconnecting the ends of a band or of the'band and the seg-- ments.

Other objects, advantages, capabilities and features are comprehendedbythe invention as will later appear and are inherently possessedthereby.

Referring to the drawings, Fig. 1 is a perspective view of a heater orfurnace using bands constructed in accordance with the invent-ion.

Fig. 2 is a fragmentary sectional view. through a part of the sect-ionsof a heater and a band in place.

-Fig. 3 ,is a horizontal sectional through apart of the band.

Fig. 4 is a perspective view of a band slgowing the construction of theends there- 0 Fig. 5 is a fragmentary perspective view of partlyconnected ends of the band or an end of a band with an end of a segment.

Fig. 6 is a similar viewv of the. connection shown completed And, Fig. 7is a view in spaced assembly and perspective showing the relation of theendsof a band and an interposed segment. before connection thereof tothe ends of the band.

Referring now, more in particular to the drawings, the embodimentselected to illustrate the invention is shown asv in the form of a bandhaving a. main portion 1 preferably of cylindrical form and parted in .aplane passing through the axis of the band. the band comprising anintermediate channel portion'2 which acts as a support or separatingmember between the sections 8 view 1926. Serial N0. 120,036.

and i and 3 and 5 ofa furnace or heater, and appearing as a rib attheexterior of the heater as clearly shown in Figs. 1 and 2 of thedrawings. WVhen in position in the heater, the flanged portions 6 and 7of the band are located interiorly of the sections of the heater andengaging the interior sides thereof, the inherent resiliency of the bandcausing the flanges of the band to constantly press against the innersurface of the seotio'ns. The rib or channel portion 2 will eX- tendoutwardly so that the lower end of a section, such-as the lower end 8will rest up on the top face 9 of the rib 2 and the upper end 10 of thelower section will contact with and support the lower face 11 of the rib2,

" as clearly shown in Fig. 2 of the drawings.

The main or major portion of the band is provided with ends 12 and 13 ofwhich the former is preferably provided with apertures 14 formed in theflange portions 6 and 7, and also with adjacent depressed or chan n'eledportions 15 preferably located adjacent to the apertures 14., and theother'end 13 being preferably formed with integral tongues orprojections 16 extending circumferentially from the ends of the flangedportions 6 and 7, as clearly shown in Fig. a of the drawings. Thetongues 16 are preferably curved as more clearly shown in Fig. 4 of thedrawings, for facilitating the entry of the ends of the tongues into theapertures 14. j

When applying the band to a, furnacehaving sections of the smallestsize, it is not necessary to use an interposed segment, but the tongues16 can be directly connected to the other end of the band by theinsertion of the ends 17 of the tongues through the apertures 14 so thatthe body portion of the tongues will fit into the depressed portions 15.and then the ends 17 of the tongues may 1 lie laterally bent as shown inFig. 5 of the drawings, and then hammered over to form the hookedportions 17 as shown in Fig. 6 of the drawings, these hooked portionsthus clasping the inner surface of the depressed portions 15 whereby theconnection cannot be readily disengaged.

In the event of using the bands in a furnace having sections of largersize, the band may be expanded to form a gap be tween the ends of theband and a segment 18 may be used to fill this gap. The segment 18ispreferably provided with flange the band desired to fit the particularsize of sections of the heater.

The opposite ends of the segments are provided with connecting meansrespectlvely the same as at the endsof the major portion of the band,one end being provided with apertures 14 and depressed portions 15adapted to be connected with the tongues 16 of the band in exactly thesame manner as previously described when the parts 14 and 15 of the bandwere connected. The other end of the section has tongues 16 with ends 17of the tongues curved to enter into the apertures 14 and channel ordepressed portions 15 of the adjacent end of the band body portion. 1 g

It will be apparent from Fig. 7 of the drawings that the tongues at theright hand end of the segment 18 will. enter into and be connected tothe end of the main part of theband shown at the right hand side of thesegment, and that the tongues 16 on the otherend of the main portion ofthe band and shown at the left hand side of the segment 18 may enterinto and be connected to the left hand end. of said segment, as shown insaid figure. The ends of the tongues may be bent over into the form of ahook in the manner above described in connection with Figs. 5 and 6 ofthe drawings.

While I have herein described and upon the drawings shown a particularembodiment of the invention, it is to be understood that the latter isnot limited thereto but comprehends other constructions, details,features and arrangements of parts without departingfrom the spiritthereof.

Having thus disclosed the invention, I claim: e I I 1. A joining means,comprising a band of circumferential form and having mutually engageableabutting ends. one of said ends having an aperture and a depressedportion. the other of said ends having a tongue adapted to fit into saiddepressed portion and extend through said aperture.

2. A joining means, comprising a band of circumferential form and havingmutually engageable abutting ends, one of said ends having an apertureand a depressed portion, the other of said ends having a tongue adaptedto fit into said depressed portion and extend through said aperture. theprojecting end portion of said tongue beingadapted to be bent to form ahook clasping said depressed portion.

A joining means. comprising a band portion and a rib portion both ofcircumferential form and parted in an axial plane, and means at the endsof said band portion for mutually connecting said ends together 41. Aconnecting means for joining bands,

comprising end portions of a band adapted to be connected together inabutting relation, one of said end portions having an aperture, and adepressed portion adjacent said aperture, the other of said end portionshaving a projection adapted to extend through said aperture and to fitinto-said depressed portion, the end of said projection being adapt, edto be bent to form a hood to clasp said depressed portion.
